We used private money and seller finance for acquisition, raised rents, renovated one building, and sold each building separately as 4 unit buildings.

I currently have two rentals that are cash flow positive running at 6.7% and 8% ROI.

Also, any suggestions for ways to save money on the repair? 

I would appreciate references to experienced professionals (architects, arborists, GC, surveyors etc.) who can help me negotiate and get permits for a short plat in Bellevue, WA. 

I'm the broker, developer, and run it from start to finish How did you finance this deal?

But again, I run into the above questions when I try to implement details and no one in uDirectIRA would tell me how this works.

I have experience in construction and rehab projects so would plan on doing a lot of my own work and subcontracting out the rest to save money vs the alternative of hiring a contractor to do the whole project. 

Even IF (BIG if) their method can be successfully utilized, without the right knowledge/ education you won’t be able to utilize it profitably, at least not for the long run.

I want to move to a single family (maybe build the house) but I don't have a ton of money saved (only 15k) because most of my money has been going into fixing it up.

I do expect this will cost me more (possibly much more) in the short term than offering cash for keys.
